摘要

Abstract

<正> AIM:To explore the more accurate lung sounds auscultation technology in high battlefield noise environment. METHODS: In this study

we restrain high background noise using a new method-adaptive noise canceling based on independent component analysis （ ANC-ICA）

the method

by incorporating both second-order and higher-order statistics can remove noise components of the primary input signal based on statistical independence. RESULTS: The algorithm retained the local feature of lung sounds while eliminating high background noise

and performed more effectively than the conventional LMS algorithm. CONCLUSION: This method can cancel high battlefield noise of lung sounds effectively thus can help diagnose lung disease more accurately.
